What this tool does A comprehensive set of router bits designed to cut decorative profiles, including crown moldings and architectural picture frame molding. The set covers a full range of sizes so you can match multiple molding profiles and trim details. Key benefits — why you need it Precision results: sealed bearings ensure uniform rotation and accurate, repeatable cutouts for clean profiles. Long-lasting sharpness: premium C3 micro-grain tungsten carbide blades are heat-treated and can be re-sharpened to extend tool life. Broad compatibility: 12 mm shanks fit routers and collets that accept 12 mm router bits, making the set suitable for many benchtop and handheld routers. Low-friction, heat resistance: Teflon coating reduces heat buildup and residue on the cutter surface during use. Features and specifications Shank size: 12 mm. Blade material: C3 micro-grain tungsten carbide, heat-treated and re-sharpenable. Bearings: sealed for smooth, consistent rotation. Coating: heat-resistant Teflon finish to reduce sticking and heat. Range: large selection of essential router bit styles and a full range of sizes for molding work. Performance and care For best results, run the router at recommended speeds for the material and take light passes to preserve edge life. Avoid impacts between the alloy blade and hard surfaces (cement floors, metal surfaces). Collisions can chip the carbide cutting edge. Blades can be re-sharpened by a qualified sharpener when cutting performance decreases. Typical applications Cut crown molding profiles to upgrade room trim and transitions in living rooms, dining rooms, or hallways. Produce architectural picture frame molding for doors, cabinet faces, or framed wall panels. Create decorative edge profiles on furniture, shelving, and custom millwork where precise, repeatable profiles are required. Why this set stands out Combines professional-grade carbide (C3 micro-grain) with sealed bearings and a heat-resistant coating for durable, precise performance across a wide variety of molding and trim projects.
